“Any connection between that vehicle and Card is unsubstantiated at this time. Originated in Oxford Maine. Passed on in an abundance of caution and we are gathering more info but as of right now unsubstantiated,” a Massachusetts State Police spokesman said in a statement.

Windham, New Hampshire police added additional details. They said the “concerned citizen” thought they might have seen a person matching Card’s description while in the area of Exit 3 on I-93.

The vehicle was described as a blue Toyota with Maine regristation, but the license plate came back to a Chevy Suburban. Police determined there was “no credible information that the individual is currently in Windham.”

I-Team sources previously reported that Card has ties to Massachusetts, though the exact nature of the ties was not immediately known.

Anyone who encounters Card is asked to call 911 immediately. He is considered armed and dangerous and should not be approached.

Card is described as 5’11” tall, weighing 230 pounds. There have been no confirmed sightings since Wednesday night.

New Hampshire State Police said they are providing assets to help in Maine during the search.

“There is no known specific threat to the state of New Hampshire at this time, but Troopers remain vigilant and ready to respond,” police said in a statement.
